That is, the printing roll chuck hole of one of the plate holders attached to the elastic portion is manually inserted into the fixing screw of the hook portion of the printing roll plate cylinder, and the fixing screw is manually inserted into the fixing screw. Tighten and fix, and also insert the printing roll chuck hole of the other plate holder into the tension screw of the tension part of the printing roll by hand, and turn the tension screw by hand to move the tension part. In this way, tension is applied to the elastic portion, and the elastic plate for forming a thin film is attached to the printing roll plate cylinder. Also, when removing the elastic plate for forming a thin film from the printing roll plate cylinder, the tension applied to the elastic part is relaxed by manually turning the tension screw of the tension part and moving the tension part. Then, loosen the fixing screw by hand to release the fixing, remove the plate holder manually from the hook portion and the tension portion of the printing roll plate cylinder, and remove the plate holder from the printing roll plate cylinder. Is to remove it.

Such a conventional thin film forming apparatus has the following problems.

(1) As described above, the chuck device including the hook portion and the tension portion provided on the conventional printing roll plate cylinder has only the fixing screw and the pulling screw. To fix or release the elastic plate for thin film formation on the body, use a person's hand to tighten or loosen the fixing screw. Or turn it on. Therefore, it takes time and effort to fix and release the thin film forming elastic plate on the printing roll plate cylinder, and the efficiency is low.

(2) In the conventional chuck device, when fixing the thin film forming elastic plate to the printing roll plate cylinder, first, the operation of pressing the plate holder of the thin film forming elastic plate against the printing roll plate cylinder is performed. By tightening the fixing screw by hand After this operation is completed, the operation of pulling the elastic plate on the printing roll plate cylinder to prevent wrinkles from occurring is performed by rotating the pulling screw by hand. is there. If these two operations are not performed in this order, for example, the elastic plate may be pulled while the plate holder is floating from the printing roll plate cylinder, or the rotary screw may not fit into the printing roll chuck hole of the plate holder. Inconvenience occurs.

Therefore, when fixing the elastic plate for forming a thin film to the printing roll plate cylinder, the screw must be rotated twice by hand, taking into account the sequence of screw rotation. It is troublesome and inefficient to fix the elastic plate for thin film formation on the cylinder.

Also, when releasing the fixation of the thin film forming elastic plate on the printing roll plate cylinder, first, the operation of releasing the tension applied to the elastic portion is performed by rotating the pulling screw by hand. After the operation is completed, the operation of eliminating the press of the plate holder against the printing roll plate cylinder is performed by loosening the fixing screw by hand. If these two operations are not performed in this order, for example, there is a disadvantage that the rotary screw cannot be removed from the printing roll chuck hole of the plate holder.

Therefore, when releasing the fixation of the thin film forming elastic plate on the printing roll plate cylinder, it is necessary to perform the operation of rotating the screw twice by hand, taking into account the sequence of rotating the screw.

As described above, in the prior art, it is very troublesome and inefficient to fix or release the thin plate forming elastic plate on the printing roll plate cylinder.

The first chuck member 25 and the first drive unit 26 correspond to the number of the first printing roll chuck holes 80 provided in the first plate holder 12 of the thin plate forming elastic plate 5 12. Provided. In this embodiment, the first mounting table 19 and the first chuck member 25 are provided at both ends of the printing roll plate cylinder 503.

The first chuck means 1 2 is formed as follows. W

Installed at 506. That is, as shown in FIG. 4 and FIG. 5, the base plate mounting member 5 10 is fixed to both end surfaces of the printing roll plate cylinder 503 in the groove 506. The base plate mounting member 501 is a member for supporting and fixing both ends of the first base plate 509 extending along the groove 506, and as shown in the drawing, the printing roll plate cylinder 5 The first base plate 509 is inclined at a predetermined angle so that the first base plate 509 becomes a downward slope along the clockwise direction with respect to the tangential direction to the peripheral surface of the third surface. Thus, the first chuck means 12 is mounted on the first base plate 509 fixed to the printing roll plate cylinder 503.

The first base plate 509 has an example of a second guide member extending in the axial direction of the printing roll plate cylinder 503 along one side in the longitudinal direction of the first base plate 509. The slide guide 201 is fixed. The slide guide 201 has a guide groove 231, which engages with the slide guide 201, and a second slider 23 that slides along the slide guide 201. Can be Further, cam followers 230 are rotatably mounted on the upper surfaces of both ends of the second slider 23. Such a second slider 23 is driven by a drive shaft of a cylinder 24 which is an example of a drive device such as an air cylinder and an oil cylinder, which is attached to the support frame 502, for example. The second slider 23 and the cylinder 24 are components of the first drive unit 26 described below.

Hereinafter, the first mounting table 19, the first chuck member 25, and the first drive unit 26 provided in the first chuck means 12 will be described.

First, the first driving section 26 has a second base plate 20, a first slider 21, and a compression spring 22, in addition to the above-described second slider 23 and the like. As shown in FIG. 7, the second base plate 20 is fixed at both ends of the first base plate 509 and at positions where they do not interfere with the second slider 23. Figures 5, 7 and 8 show As described above, a guide 511 which is an example of a first guide member extending in a direction orthogonal to the moving direction of the second slider 23 is fixed on the second base plate 20. A first slider 21 that engages with the guide 5 11 and slides along the guide 5 11 is attached to the guide 5 11. On the upper surface of the first slider 21, a first chuck member 25 is erected, so that the first chuck member 25 is orthogonal to the moving direction of the second slider 23 together with the first slider 21. Go to In addition, one end of the first slider 21 extends up to above the second slider 23 so as to contact the cam follower 230 provided on the second slider 23, and as shown in FIG. The inclined surface 2 11 is formed so that the first slider 21 moves in the direction of the arrow VI when the second slider 23 moves in the direction of the arrow V. Also, the elastic force of the compression spring 22 provided between the panel stopper 200 erected on the second base plate 20 and the spring stopper 210 fixed to the first slider 21 causes The inclined surface 2 1 1 of the first slider 21 is always biased toward the cam follower 230.

The first chuck member 25 is a force that vertically pushes the opening edge 27 of the first printing roll chuck hole 80 of the first plate holder 2 of the thin film forming elastic plate 5 12 toward the first mounting table 19. And a claw portion 18 for adding

The first mounting table 19 has a through hole 180 through which the first chuck member 25 penetrates, and as shown in FIG. 4, a first base plate is provided so as to substantially cover the first slider 21 and the like described above. 509 or a pair of support frames 5 13 erected on the second base plate 20. On the upper surface of the first mounting table 19, as shown in FIGS. 2, 15 and 16, the mounting position of the thin film forming elastic plate 5 12 with respect to the printing roll plate cylinder 503 is determined. A pair of positioning pins 14 may be provided upright.

Further, as described above and as shown in FIG. 5, in the first chuck means 12, W

Although the first slider 21 and the first chuck member 25 are all inclined with the inclination of the first base plate 509, the first mounting table 19 is a printing roll. It is arranged parallel to the tangential direction of the peripheral surface of the plate cylinder 503. The reason for disposing the first base plate 509 and the like and inclining the first mounting table 19 in the same direction as the tangential direction without inclining the same is that the claw portion 18 of the first chuck member 25 is used. This causes a downward force in the direction shown by the arrow in FIG. 19 to be generated at the opening edge 27 of the first printing roll chuck hole 80 by the above method. If a downward force can be generated, the first base plate 509 and the like need not necessarily be inclined.

FIGS. 7 and 8 are diagrams used for describing both the first chuck means 12 and a second chuck means 13 described later, and the configuration is slightly different from the configuration shown in FIG. 5 and the like. There is a point. 7 and 8, the illustration of the first and second mounting tables 19, 190 is omitted.

The first chuck member 25, the first driving unit 26, and the first plate holder 2 set on the first mounting table 19 configured as described above operate as follows (see FIG. 1). 17 to Figure 19).

That is, as described above, the inclined surface 2 11 of the first slider 21 is constantly pressed against the cam follower 230 by the compression spring 22. By pressing the second slider 23 in the direction of arrow V shown in FIG. 7 with the cylinder 24, the second slider 23 moves along the slide guide 201, and the cam follower 2 of the second slider 23 is moved. 30 pushes the inclined surface 2 1 1 of the first slider 2 1. With this pushing force, the first slider 21 moves in the direction of arrow VI while being guided by the guide 5 11 against the repulsive force of the compression spring 22. Since the first chuck member 25 is fixed to the first slider 21, the first chuck member 25 also moves in the direction of the arrow VI with the movement of the first slider 21. On the other hand, when the force of pressing the second slider 23 by the cylinder 24 is weakened, the first slider 21 moves in the direction of arrow により due to the repulsive force of the compression panel 22 and the second slider 23 moves in the direction of arrow IV. Moving. Here, since the first chuck member 25 is inclined with respect to the first mounting table 19, it moves downward and to the right in FIG. 18, that is, moves obliquely with respect to the printing roll plate cylinder 53. It can be done. As a result, as shown in FIG. 19, the opening edge portion 27 of the first printing roll chuck hole 80 of the first plate holder 12 is pressed in the direction of the arrow by the claw portion 18 of the first chuck member 25. It is. The downward pushing force indicated by the arrow is a force for pinching the first plate holder 2 in cooperation with the first mounting table 19.

When the force that presses the second slider 23 again by the cylinder 24 becomes larger than the repulsion force of the compression panel 22, the first slider 21 piles on the repulsion force of the compression spring 22, and as shown in FIG.
